Several lunch box forms are available through your local craft or hobby store. If selecting a metal box, use a strong adhesive such as 3-M® Super 77 Spray. (The formula is intended for a broad range of surfaces and is higher in tack than other aerosols.) Another option is to print your design onto inkjet matte paper with adhesive backing. You can then apply it directly to the box, or apply it to blank magnetic sheets, allowing you to change the arrangement of your design.
If selecting a paper-mache form, you may want to paint the surface first. Begin by priming the box with gesso. (Two coats may be necessary.) Allow to dry completely before covering with acrylic paint. Adhere image to paper-mache box using spray adhesive. Paper-mache boxes also work well as a surface for collage. The surface may be covered with scrap pieces of gift wrap or tissue paper. If working in a collage style, it is best to select thin or lightweight papers that will wrap easily around sides and corners. To adhere papers, choose a thin craft glue. Apply with a foam brush and press firmly in place.
